DAVID M. LEAUH AND VVINFIELD S. SLINKER, OF SULPHUR WVELIJ, KY.

WHEAT-CLEANING MACHINE.

SPECIFICATION forming part of Letters Patent No. 242,339, dated May 31, 1881.

I Application filed October 23, 1880. (Model) T all whom it may concern Be it known that we, D. M. 'LEAGH and IV. S. SLINKER, both of SulphurWell, in the county of Metcalf and State of Kentucky, have invented a new and valuable Improvement in Wheat- Gleaners and we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being bad to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a side view of a machine in which this invenformed.

tion is incorporated. Fig. 2 is a vertical longitudinal section, and Fig. 3 is a vertical transverse section of the same.

This invention relates to devices for cleaning wheat and other grain.

It consists in the construction hereinafter specified.

In the annexed drawings, A is a box or closed frame containing my devices. The top is open, and across the same is a slanting reciprocating riddle, B, abovewhich is the hopper 0. At its upper end this riddle is hinged to the frame by pins passing through loops on the frame. Extending from this end of the riddle, across the same and to its lower end, is a pliant rod, D, fastened at the upper end of the riddle, and at its other end to a crank on shaft E. By making this red D pliant, while the riddle is shaken the pliancy of the rod gives to the riddle a quivering motion, which keeps the imposed matter agitated and causes the riddle to act like a sifter. At its lower end the riddle B has a pin, 1), which engages with a spring, F, fastened to the frame A. The shaft E turns in bearings c c, and has a pulley, 0

Below riddle l), and slanting in the opposite direction, is an apron, H. The lower edge, 71, of this apron projects under the inner partition, '5, of a wind-chute, I, the side edge, It, bein g on a slant with the lower edge of said partition, so as to make the edges meet at one end and be apart at the other, whereby a wedgeshaped opening, it, into said wind-chute I is This chute I extends up beyond the opening 0 to the top of the frame A, and opens into an outlet-chute, K. The chute I extends downward and leads into a chamber, L. The

bottom of this chamber has a concave, M,with perforations m. Leading from the end of windchute I, immediately below the larger part of opening h, and extending obliquely across a portion of the face of perforated concave M, is a spout, N. By making the opening wedge shape and putting spout N just under the Projecting longitudinally through chamber L is a shaft, T, journaled in bearings at each end and having rigidly affixed to it the heaters t t and fan V, the heaters being above the concave M and the fan above the inclined hopper It. 7

To one end of shaft T is a driving pulley or crank and at the other a pulley engaging by a belt the pulley 0 upon shaft E. In the frame are suitable openings to admit air, and others for viewing the operation of the device.

Grain is poured into the hopper O, which guides it down to the riddle B. Falling upon this, it is agitated by the reciprocating of the same, and the grain, fine dirt, smut, and other small particles fall through the openings in the riddle, and large particles slide off and drop to the ground. Passin gfrom the riddle through opening h into wind-spout I, the grain and small particles come in contact with wind driven up by fan V, whereby the dust and small particles of smut unbroken are driven up to the top andout at chute K. The grain and other and heavier particles of dirt slide down chute I and through spoutNto the upper part of concave M. Sliding down this, the grain and dirt are operated upon by the heaters, which break the dirt up, an d as they fallthrou gh inclined hopper It the fan drives the dirt up through end 8 of spout S, the wheat falling down through end 8. The shape given the opening from the grain-board H to the chute I and the construction and location of the fan below cause the greatest volume of grain to fall at the point of the strongest blast, whereby it is better winnowed and more thoroughly chute is brought into contact with the strongcleansed. est blast.
